Abstract — Developer, manager and user feedback is needed to optimize products. Besides the basic Software qualities – usability and user experience are important properties for improving your product. Usability is well known and can be tested with e.g. a usability test or an expert review. In contrast user experience describes the whole impact a product has on the end-user. The timeline goes from before, while and after the use of a product. We present a tool that allows you to evaluate the user experience of a product with little effort. Furthermore the tool is available in different languages and we are using the new Spanish Version. We show how this tool can be used for a continuous user experience assessment. Keywords — Software Quality, User Questionnaire, Usability, Test, Development
S your redesign of the website better than the old version? Has the development effort spent to increase user experience really paid off? If you want to answer such questions you need a quantitative method to measure user experience . An efficient and inexpensive method to do such measurements is the usage of rigorously constructed and validated questionnaires. The concept of user experience combines well-known aspects like efficiency and effectiveness with additional criteria like aesthetics, joy-of-use or attractiveness. The first group of criteria is often referred as pragmatic quality aspects , while the second group is called hedonic quality aspects. Another often-used terminology to distinguish both classes of quality criteria is usability goals versus user experience goals . The dependency of pragmatic and hedonic quality is presented in Fig. 1. One well investigated research question is the relationship of pragmatic and hedonic quality. Empirical evidence proves that products, which are perceived to show a high level of hedonic quality, are also perceived as easy to use , , . These and similar observations cause some authors  to state that ‘What is beautiful is usable’. In contrast other studies point out ,  an opposite dependency. The perception of the aesthetic value of a user interface increased when the
number of concrete usability problems decreased. Thus, in this study a ‘What is usable is beautiful’ effect was observed.

Why are perceived hedonic and pragmatic quality aspects associated? As possible explanation for this connection haloeffects , mediation by the mood of the user  or mediation by other variables  have been suggested. Since it is quite difficult to separate these effects experimentally  it is currently unclear which of these hypotheses are able to explain this effect. These results indicate that it is necessary to consider both pragmatic and hedonic aspects if we want to measure how satisfied users are with a given product. This is the underlined idea of constructing the User Experience Questionnaire (UEQ) ,  that is described in this paper. In the context of the questionnaire user experience is understood as the overall impression of a user when he or she interacts with a product, i.e. covers both pragmatic and hedonic quality aspects. The UEQ allows a quick assessment of the user experience for any interactive product. The scales of the questionnaire are designed to cover a comprehensive impression of user experience. The questionnaire format supports the user response to immediately
